Mango e avocado nuove acquisizioni sulla coltivazione in Sicilia
L’incremento delle temperature rende possibile l’adattamento biologico-colturale. Le scelte varietali e le tecniche agronomiche sostenibili che stanno dietro alla diffusione di nuovi impianti. Mango e avocado sono tra le specie più interessanti nel panorama della moderna frutticoltura italiana. Di seguito si riportano alcune considerazioni sulla coltivazione.
Preliminary evaluation of a zinc-copper-citric acid biocomplex for the control of Plenodomus tracheiphilus causal agent of citrus mal secco disease
In this study we evaluated a zinc copper-citric acid biocomplex (Dentamet®) for the effect on citrus mal secco disease caused by Plenodomus tracheiphilus. In vitro tests highlighted an inhibitory activity of the compound on mycelial growth and phialoconidia germination. Independent in vivo trials were performed in a growth chamber inoculating a virulent fungal isolate on sour orange seedlings and young plants of two lines of Femminello lemon, namely ‘Zagara bianca’ and ‘2Kr’, grafted on sour orange and grown in pots. The compound was leaf sprayed three days before the inoculation by wounds with phialoconidia. Overall, disease index and disease progress curve in plants inoculated with P. tra…
Anthocyanin profile and antioxidant activity of freshly squeezed pomegranate (Punica Granatum L.) Juices of sicilian and Spanish provenances
Pomegranate (Punica granatum L., Punicaceae) fruit is traditionally consumed in several countries, especially in Middle East, and has gained increasing popularity all over the world due to its assumed health benefits. Juices derived from the arils of the seeds were shown to be rich in anthocyanin glucosides, typically composed of cyanidin, delphinidin, and pelargonidin. The aim of the present study was the characterization of diverse Sicilian and Spanish pomegranate accessions regarding their anthocyanin and total polyphenol contents using the Folin-Ciocalteu reagent. The anthocyanin profiles were determined by HPLC-DAD and LC-MS, and color parameters were characterized using the CIELAB coo…
